PRI Call Failing via ISR voice gateway

Hi,

I think you need to investigate further by having "debug isdn q931" and "debug isdn q921" at both gateways. There could be multiple reasons for this error which are described in below link. Traces will help us to come to a conclusion.

And on the VOIP dial peers on both routers

add
